Introduction To SAP R/3 Basis
-----------------------------------------------------------
Understanding Basis
Basis
is like an operating system for R/3. It sits between the ABAP/4 code
and the computer's operating system. SAP likes to call it
middleware
because it sits in the middle, between ABAP/4 and the operating system.

Introduction To SAP R/3 Basis
-----------------------------------------------------------
Basis sitting between ABAP/4 and the operating system. ABAP/4 cannot
run directly on an operating system. It requires a set of programs
(collectively called Basis) to load, interpret, and buffer its input and output.
Without Basis, ABAP/4 programs cannot run. When the operator starts up
R/3, you can think of him as starting up Basis. Basis is a collection of R/3
system programs that present you with an interface. Using this interface the
user can start ABAP/4 programs.
Basis makes ABAP/4 programs portable.
